iPad says Successful, iCloud says incomplete

Hello,

I am concerned about my iCloud backup. I recently restored to a different device.

The iPad says the device was successfully backed up after my restore. iCloud, on the other hand, said the device backup is incomplete.

There is a discrepancy between iCloud and iPad. It is also reflected in the LINE app where LINE says latest backup is 178KB but iCloud says 174.2KB.

Is the backup usable?

Thank you.
